Add the beer to a saucepan over medium heat and bring to a simmer. Slowly add the cheese mixture one handful at a time, whisking well to combine. Stir in the nutmeg, garlic salt and pepper.

Stir over low heat until smooth and all the cheese is melted. When to mixture starts to bubble, transfer to a fondue pot and you are ready for dipping. Serve with bread cubes, sliced vegetables and strips of meat. Continue to stir frequently.<
